One of Johnnie To's earlier films, this tale is more akin to the hard crime thriller of Martin Scorsese rather than To's recent "tongue-in- cheek" style. What we have here is brutal storytelling of blackmail, espionage, corruption, and violence all facing one struggling Hong Kong detective. Even by today's standards the violence is both shocking and disturbing to see. Some sequences may be over the top, and while out of place they are vastly entertaining. The plot of "a washed-up cop pulled back in for one last job" had been done to death even back in 1988, however Johnnie To added in some twists plus heavy suspense to make the material fresh. In my opinion the faults are the editing and lack of charisma from Waise Lee's character. The protagonist could have been more likable to better engage the audience, and the editing is dated with some awkward cuts and sped up/slowed down moments which don't blend well with the drama. Other than that the material hit home with me, and the all-out conclusion left me in awe. Keep in mind this is filled with winding clues and bloody confrontations, not an easy watch. -7/10
